It's a simple proposal to coordinate the actions of active Catalyst members who are also "one foot in another chain".
This proposal helps coordinate the efforts and incentivizes needed action. It paves the way to the next leg of Cross-Chain Collaboration:

Catalyst members might become competitive and try to be the first one to bring in cross-chain collaborators. That's why the incentive is set so low. Also, it will be communicated that if several people have approached a certain community, they will share the incentive. That's why it's better to do the coordination first and then only start reaching out.
Another "risk" is that there might not be enough Finders to claim the finder's fees. Should there be less than 10 cross-chain projects/communities/chains onboarded by the end of Fund9 submission deadline, the other Finders will then share the unclaimed fees. I.e. if there are only five people who bring in proposer teams from other blockchains, they each will be rewarded $1,000 each.
